□ Example:
1. Input: Voltage DC 50V Current 20A W=50*20= 1000 W
Set 01(Voltage ratio) as 5000
02(Current ratio) as 2000
03(Watt ratio ) as 1 (unit is W)
04(Decimal point) as 0 2 2 0 V= 50.00 A= 20.00 W= 1000
2. Input: Voltage DC 600V Current 1000A/50mv W=600V*1000A=600.0KW
Set 01(Voltage ratio) as 6000
02(Current ratio) as 1000
03(Watt ratio ) as 6000 (unit is KW)
04(Decimal point) as 0 1 0 1 V=600.0 A=1000 W=600.0KW
Note:
*All parameters were preset by our factory according to your order specifications.
